Motors

Motors transform the electrical power from the traction system to mechanical power to get the train moving: Alstom motors enable trains to operate at speeds of up to 574.8 km/h (World rail speed record set by Alstom/SNCF and RFF on April 3, 2007).

Leader in permanent magnet motor technology

Combining the widest spectrum of applications for permanent magnet motors (PMM) with the return on experience of more than 3,000 PMMs in service, Alstom is today the unrivalled leader of PMM technology in railway applications.

High power density enabling for instance innovative architectures thanks to reduced motorisation rate

Permanent magnet motors are key to the successes of a wide range of Alstom trains fro tramway applications to very high speed ones.

Innovative and long-lasting railway motors

Our motor engineering centre at Ornans (France) is the heart of Alstom’s motor innovations: the Ornans site has been designing best-in-class motors since 1919. Its cutting-edge validation facilities guarantee that even our most innovative products are reliable: Validation of the motor within its traction system, bearings fatigue test bench, fatigue test bench to validate new concepts, semi-anechoic chamber for noise performance deep validation.

Close to our customers

Alstom supports its customer projects via a network of ISO 9001-certified manufacturing locations, while retaining a single design authority. In addition to its historical manufacturing centres in France (Ornans) and USA (Hornell, NY), Alstom has created a joint venture in China (Xian): Xayeeco has produced nearly 7,500 motors since its creation in 2006.

Alstom accompanies its customers by offering a range of customised services for their trains and sub-systems – whether built by Alstom or not – throughout the entire lifecycle. Thanks to our catalogue of motor spare parts and our full range of maintenance and overhaul expertise, we help our customers to stay focused on their core business while minimising the lifecycle costs of their equipment.
